alpine docker 代理设置（linux通用）

linux系统代理

------------------设置----------------------
vi /etc/profile.d/proxy.sh

# 1. 定义基础代理地址 http_proxy 也可以走 socks5h://
_proxy_url="socks5h://192.168.1.120:7890"

# 2. 导出小写版本
export http_proxy="$_proxy_url"
export https_proxy="$_proxy_url"
export ftp_proxy="$_proxy_url"
export all_proxy="$_proxy_url"

# 3. 导出大写版本（为了兼容 Docker, Go, Java 等）
export HTTP_PROXY="$_proxy_url"
export HTTPS_PROXY="$_proxy_url"
export FTP_PROXY="$_proxy_url"
export ALL_PROXY="$_proxy_url"

# 4. 你的绕过配置
export no_proxy="localhost,127.0.0.1,::1,192.168.0.0/16,172.16.0.0/12,10.0.0.0/8,\
aliyun.com,aliyuncs.com,taobao.com,aliyun-inc.com,\
tencent.com,qq.com,cloud.tencent.com,cos.ap-*.myqcloud.com,\
huaweicloud.com,huawei.com,obs.cn-north-1.myhuaweicloud.com,\
163.com,netease.com,cloud.163.com,\
gitee.com,gitcode.net,mirrors.ustc.edu.cn,mirror.tuna.tsinghua.edu.cn,\
npm.taobao.org,registry.npmmirror.com,\
cnpmjs.org,segmentfault.com,csdn.net,oschina.net,\
baidu.com,bilibili.com,zhihu.com,.atibm.com,.kc.com"
export NO_PROXY="$no_proxy"

------------------生效----------------------
sudo chmod +x /etc/profile.d/proxy.sh;source /etc/profile.d/proxy.sh

------------------验证----------------------
echo $ALL_PROXY
nc -zv 192.168.1.142 7890					# 代理联通性
curl -vso /dev/null https://www.baidu.com	# 访问内网
curl -vso /dev/null https://1.1.1.1			# 访问外网
curl -vso /dev/null https://www.google.com	# 访问google
time curl -o /dev/null -s https://www.google.com	# google测速
